Should Have Bought is a “missed investment and opportunity cost calculator.” Users enter a USD amount, select an asset, and choose buy and sell dates to calculate the difference in returns if they had bought at the time—or had not sold. It covers crypto assets such as Bitcoin, Ethereum, Solana, and Dogecoin, as well as traditional assets like NVIDIA and GLD. The site states that its data source is Gemini Exchange, and the core product is a web-based tool built with Laravel/PHP and Alpine.js.
In terms of platform type, it is not an exchange, wallet, or DeFi protocol, but rather a historical price backtesting and sharing tool. As such, it does not offer order placement, custody, deposits, withdrawals, lending, staking, or on-chain interactions. For supported assets, the text lists BTC, ETH, SOL, and DOGE, but does not disclose specific trading pairs or clarify whether more assets are supported. There is no relevant disclosure on fees, KYC, security measures, cold wallets, insurance, regulatory licenses, derivatives, or leverage, since it is not fundamentally a trading platform.
It is not stated whether the calculator itself is paid. The website also offers a “Survivors Club” sidebar advertising service for crypto and finance brands, with 7 ad slots. Weekly pricing is around $500–1,000, monthly pricing around $2,000–3,000, and lifetime placements are negotiable. Ad payments support Stripe (card/invoice), BTC, ETH, SOL, and wire transfer on request.
Its strengths are a clear positioning and simple user flow. It is suitable for quickly checking the opportunity cost of missing assets such as BTC or ETH, and it can generate shareable links, giving it strong social distribution potential. Its drawbacks are that the product is more entertainment- and emotion-driven, with copy centered on “regret/FOMO.” It lacks investment education, risk warnings, explanations of potential data errors, and clarity on pricing methodology. If users mistake it for investment advice or a trading entry point, it may lead to misunderstandings.
It is suitable for ordinary investors who want to review historical asset performance or create social sharing content, as well as crypto/finance brands looking to buy exposure. It is not suitable for users who need trade execution, asset custody, fiat on/off-ramps, leverage, or a regulated account system. The text does not provide information on access from mainland China, so network availability cannot be determined. If access is restricted, alternatives such as CoinMarketCap, CoinGecko, TradingView, or exchange candlestick chart tools may be considered.
